11.1 Preface
The purpose of this section is to provide basic repair instructions for minor
damage to GFRP gliders. (Glass fibre reinforced plastics). Detailed
information regarding all the processing of GFRP is not given in this
manual assuming that all repair work will only be carried out by people
with practical knowledge in the use of these materials.
The repair of gliders should not be used to learn FRP laminating
techniques.
Before beginning any repair work carefully determine what materials, tools,
jigs and repair methods are to be used. The required information can be
found in this manual. To insure that the aircraft performance is maintained,
the surface finish of the repair work should be of the same quality as the
original finish.
When doubts arise as to the repair ability of damage, the DG Flugzeugbau
factory should be contacted for further information.
The information in this manual refers only to repairs of minor damage like
holes in the underside of the fuselage resulting from a wheel up landing, or
damage from hangar accidents etc, see section 2.
Major damage which is outside the scope of this manual should only be
repaired by a certified repair station or by an approved mechanic rated for
composite aircraft structure work.
Note: For repair- and servicing work on parts of the equipment. the instructions
in the maintenance manual of the aircraft and the manuals belonging to the
equipment parts are to be followed.
